I don't show every step here. Some steps I show are optional and you can find your best way. The STEP file has a kickstand feature. We did not use this, rather, as shown at the end of the video, we used a crank to flip the sheep. This is far easier on the body than trying to heave each sheep up to the 90 degree mark. The audio isn't the greatest, so apologies in advance. Some elements of the BOM may be out of date (e.g. the ref to the 2" tube instead of the 1.5" tube). Total cost to build this in 2023 was around $350-$400. The steel alone was ~$280. We did buy new steel. You don't need to do this. Add in plywood, rubber, paint, pins, primer, hooks, screws, the crank (if used), welding wire, alignment jigs, and any additional infrastructure needed. This is still far cheaper than a commercial solution and with some practice works very well. If you have questions, please leave a comment. In general, we are hobby farmers working with the tools we have. I acknowledge there are likely better ways to do things than the way I did them. If you know a better way - do it. A note about the rubber - we bought a bulk amount at Lowes.
